Tooltiplingo

About

Learn vocabulary naturally while you browse the web.

Tooltiplingo turns every webpage into a language learning opportunity. Simply double-click any word or phrase to instantly see its translation in a tooltip — the word is automatically saved to your personal vocabulary list and scheduled for review using the FSRS spaced repetition algorithm.

HOW IT WORKS
1. Double-click a word on any webpage to see its translation
2. The word is automatically saved with context (the surrounding sentence, source URL, and page title)
3. When words are due for review, you'll receive a reminder
4. Complete short quizzes to reinforce your memory at scientifically optimal intervals
